ENGRAVERS TOOL.

Specification of Letters Patent.

Patented Apr. t8, 191.1.

Application filed July 5, 1910. Serial No. 570,338.

To all whom it may concern:

Be it known that I, EDUARD FRnDnIoK MUELLER, citizen of the UnitedStates, residing at Caldwell, in the county of Burleson and State ofTexas, have invented certain new and useful Improvements in EngraversTools, of which the following is a specification.

My invention relates to new and useful improvements in engravers toolsand is more particularly designed to assist in holding small articles tobe engraved.

The object of my invention is to provide a device of the characterdescribed which will hold rings or other small objects to be engravedwithout marring or defacing their surface.

Another object of my invention is to provide a device of the characterdescribed which will hold a ring in such a manner that the setting willbe held in position to be removed easily or replaced.

Finally the object of the invention is to provide means of the characterdescribed that will be strong, durable, eflicient, and easy ofoperation, simple and comparatively inexpensive to construct, and alsoin which the several parts will not be likely to get out of workingorder.

With the above and other objects in view, the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in this specification and illustrated in theaccompanying drawings, wherein:

Figure 1. is a perspective view of my invention, Fig. 2. is alongitudinal section of the same, Fig. 3. is a detail of a portion ofthe band used to hold the article to be engraved showing the openingthrough which the set of a ring may be passed to admit the resettingthereof, and Fig. 4. is an end elevation of my invention with theretaining band broken away.

In the drawings, the numeral 1 designates a hollow handle terminating ina ball shaped grip 2. Within the handle 1 a sleeve 3 is fixed and heldagainst rotation. This sleeve carries an annular groove 4 at one end andinternal threads 5 at its other end. A sleeve 6 engaging over the sleeve3 is held in position by pins 7 which engage with the shoulders formedby the annular groove 4 in the sleeve 3, By turning the grip 2 the isbent to form a loop after passing through 1 a ferrule 12 which closesthe end of the sleeve 6. The shape of the steel band 11 is best shown inFig. 4 where the band is shown in section. It will be noted that whilethis band is concaved enough to prevent an object slipping therefrom, itis not concaved suiticiently to prevent the band from being drawn into acomparatively small loop without danger of kinking or bending itpermanently out of shape. The apertures 14 in the ferrule 12 are curvedto fit the concavity of the steel band, while an elongated aperture 15in the end of the ferrule designed to assist in holding articles placedbeneath the steel band, has its ends curved at substantially the sameradius.

At 16 the band 11 is enlarged or made wider and an opening 17 is cuttherein to admit the passing of the set of a ring therethrough. Thisopening 17 maybe made large enough to allow the passage of a Tiffanysetting or other two carat settings, but care must be used in selectingthe material for the band, as a band of stiff material would likely bendor buckle at this point. The ferrule is reduced in thickness on eitherside to render the end of this tool less bulky and to make the work heldin the tool more visible to the operator. These reductions are shown inFigs. 1 and land are numbered 18.

It is obvious that this tool will be of great assistance to an engraverwho wishes to make an inscription on the inner periphery of a ring aswell as to a stone setter or manufacturing jeweler who has occasion toset stones in articles which are hard to hold in position for settingwithout defacing the article. When a ring is placed in this tool oneside of the ring, no matter what its size may be, will extend into theelongated aperture 15, and the other side will be engaged by the band11, after the same has been tightened by turning the grip 2, theconcaved surface of the band in conjunction with the engagement of thering with the side walls of the aperture 15, will hold it securely inposition as well as firmly against rotation.

It is believed that it is unnecessary to describe the many uses to whichthis tool may be used since its form makes it adaptable for holdingalmost any cylindrical body.

What I claim is: r

1. In an engravers tool, a grip, a handle member formed integral withthe grip, the grip and handle having a continuous central opening, asleeve abutting the handle member and having an opening contiguous withthe opening of the grip and handle, a

tubular member engaging partly in the opening of the grip and handle andpartly in the opening of the sleeve, the tubular member being fixedagainst movement in the handle, the sleeve bein rotatable on the tubularmember, a fastening between the sleeve and the tubular member forholding the former against longitudinal movement, the sleeve having aflared recess at one end and an external shouldered portion, a drawingrod extending from the flared recess of the sleeve through the tubularmember and terminating in the opening of the grip, the drawing rodhaving screw threads at its inner end portion engaging in the inner endof tubular member, a ferrule embracing the shouldered portion of thesleeve and extending outward from the same, the ferrule having a centralring receiving opening and an opening on each side thereof, and a loopband provided with a central ring exposing opening and having its freeends passed through the side openings of the ferrule and secured to theopposite sides of the outer end of the drawing rod.

2. The combination with a handle member, of a sleeve member having aflared recess at its outer end, a tubular member fixed in the handlemember and on which the sleeve is rotatably confined, a drawing rodscrew threaded in the tubular member and having a flared head disposedin the recess of the sleeve, a ferrule fixed on the sleeve provided withan elongated central opening and a curved slot on each side thereof, anda loop band concaved in cross section provided with an enlarged centralportion having an elongated opening, the free ends of the band passingthrough the curved slots and secured on opposite sides of the head ofthe drawing rod.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDUARD FREDRIGK MUELLER.
